Figure 4. Wavelet power and in-out causal flow.

Power at slow-4 frequency (left column) and in-out flow at slow-3 frequency (right column) for regions: (A) PCC, (B) mPFC, (C) LMTC, (D) LAG. Dotted boxes are used to highlight that the higher values of power and the in-out flow originate at around the same time points but at different frequencies.
